How do I call a function in an Angularjs file using Nodejs?

I am developing a CRM application using Java, Nodejs, Angularjs. I'm using Nodejs with a Facebook Chat API and in order to retrieve a Facebook users online status legally, I have to use a different Facebook API that only works with AngularJS.

So far, using Nodejs, I pull user chat data from Facebook, save it, and parse it for keywords and phrases. All I require now is basic instruction on how to call an AngularJS function in Nodejs.

Thank you
